"The gospel is not a doctrine of the tongue, but of life. It cannot be grasped by reason and memory only, but it is fully understood when it possesses the whole soul, and penetrates to the inner recesses of the heart. Let nominal Christians cease from insulting God by boasting themselves to be what they are not, and let them show themselves disciples not unworthy of Christ, their Master. We must assign first place to the knowledge of our religion, for that is the beginning of salvation. But our religion will be unprofitable, it if does not change our heart, pervade our manners, and transform us into new creatures."
-John Calvin in his Golden Booklet of the True Christian LIfe
